Re: Thinkpad E580 - Radeon RX 550 performance issue

2019-01-11, 13:07 PM

evolution: My problem RX550 was game problem only. I can switch each any program manually between graphics (economy=intel, high performance=RX550), even can I choose my card on program startup by special shorcut icon - edit: sometimes even iside a game, Mount&blade, for example). If you run intel only, your problem should be just in configuration/drivers. The real trouble which IMHO cannot be solved without bios, is: every "game" (Witcher3, specially, but not only) which fully uses RX550 suddenly "hanged" after 5 mins play due to misidentification of overheating RX by bios - after cooling period (1-2 mins) it gets full throttle for 2-3 mins and gets overheated again. I installed monitoring - overheated=72°C, cooled down cca 60°C, full RX550 core throttle = cca 1,2GHz, cooling = 200MHz. 1.13 has no cooling period, stable 77°C and 1-1,2Ghz. Who OMG/BD programed this? Stable 77°C may be less devastating than 60-72°C oscilation, should not? 

 

jwls: Did i get your post right -

1) ThrottleStop manipulates CPU only, not RX550 GPU, but can optimalize performance more than a bit?

2) Without 1.13 RX550 makes its "cooling slowdowns" even with optimalized CPU?

1. Yeah, ThrottleStop manipulates only CPU.
2. Correct.

Same here...

I bought this machine last year and downgraded to 1.13 and am using like that since then.

I'm losing my hopes that Lenovo will ever fix that, but I'm ok using the old bios, everything working fine here.

 

Any words from bios 1.28 out there? Maybe something improved... I'm not really willing to test it.

The e580 and e480 laptops have no differences in hardware. I have e480. An annoying fan noise, overheating and throttling is the main reason I do not recommend these models for purchase. I tested all versions of the BIOS (the latest BIOS 1.31), and I did not notice any changes or improvements. I wanted to do the undervolting, but in the BIOS firmware there is a protection that prohibits making any changes. TPFanControl also does not work as I want (when the temperature exceeds 70 degrees, it loses control of the cooler control).

This is a complete failure of Lenovo. This was the first and last time I bought a laptop Lenovo :smileyfrustrated:.

I did it too, but in games it is very strong overheating (80-88°C). I am afraid that in this mode it will quickly break.

I suggest you to repaste yours. I did here and I get 75-80ºC on full load, while undervolting at -0.108.

You need to disable bios downgrade protection in bios and run the 1.13 exe. It's pretty straightforward, let us know if you have any trouble.
